CSA Certified Explosion-Proof and Intrinsically Safe for hazardous locations
The 21000-34-05-00-036-03-02 is an Aluminum Proximity Probe Housing Assembly with Canadian Standards Association approvals. It carries an explosion-proof rating for hazardous areas and applies to intrinsically safe installations. The housing functions as a certified CSA Type 4 enclosure and maintains full compliance with the American Petroleum Institute's 670 Standard for externally mounted proximity probe housings.
Threaded ports for conduit connections
Optional conduit fittings
A dome cover that screws into the body of the housing
The Bently Nevada 21000 Proximity Probe Housing Assembly fully complies with the American Petroleum Institute's (API) 670 standard for externally mounted proximity probe housings. Featuring a lightweight aluminum enclosure, this assembly is certified as a CSA Type 4 enclosure. It carries rigorous Canadian Standards Association approvals and is rated explosion-proof, making it ideal for intrinsically safe applications in hazardous areas. The sleeve length of the assembly is determined by the specific location in which the probe and housing are installed. For applications requiring sleeve lengths longer than 304 mm, additional sleeve support is necessary to mitigate mechanical vibrations associated with unsupported long sleeves.
Bently Nevada offers a standard probe support and oil seal for long sleeves routing through an inner bearing housing, as well as custom sleeve support solutions. Additionally, the product line includes the 24701 stainless steel housing and the 164818 compact housing to accommodate various material and space restrictions. As a critical hardware extension of Bently Nevada’s machinery protection systems, this assembly provides rugged physical protection for mainstream proximity probes against industrial oil, moisture, and mechanical impacts.
Its "externally adjustable" design allows for rapid probe adjustment and maintenance without removing the main housing. This minimizing equipment downtime and ensures seamless integration with the 3500 monitoring system for the long-term, safe, and stable operation of critical rotating machinery—including turbines, compressors, and fans—in harsh industrial environments.

Oil and Gas Refining
Protects proximity probes on critical unlubricated or hydro-cracked gas compressors to monitor shaft vibration and axial thrust.
Petrochemical and Chemical Processing
Monitors the rotor dynamics of high-speed centrifugal pumps handling volatile or corrosive hazardous chemicals under explosion-proof requirements.
Thermal Power Generation
Houses sensors measuring oil-film thickness, shaft vibration, and thermal expansion on large steam turbine-generator sets.
Nuclear Power Plants
Monitors critical rotating assets in the non-nuclear island to ensure uninterrupted power transmission and cooling system integrity.
Hydroelectric Power Generation
Tracks the radial runout and alignment of large vertical or horizontal hydro-turbines and generators to prevent stator-rotor rubbing.
Iron and Steel Metallurgy
Protects displacement sensors from high heat and heavy dust while monitoring large air blast blowers and exhaust fans.
The sleeve length of this assembly depends directly on the location in which the probe and housing are installed, ensuring the probe lead remains longer than the sleeve. Since the configured penetration depth is 3.6 inches, it operates within vibration limits without auxiliary bracing.
For applications where alternative configurations require unsupported sleeve lengths exceeding 304 mm (12 inches), additional sleeve support is mandatory to mitigate vibration. For installations routing through an inner bearing housing, a Bently Nevada probe support and oil seal (Part Number 37948-01) or custom sleeve supports can be utilized.
21000-34-05-00-036-03-02 features a 3.6-inch sleeve and 3/4-14 NPT fittings, providing an externally adjustable, weatherproof enclosure for precise vibration and displacement monitoring in hazardous industrial areas.
It is an externally mounted proximity probe housing assembly consisting of an aluminum body, an integrated 11 mm proximity probe, and associated fittings, utilized for industrial condition monitoring on large rotating machinery.
How is the 21000-34-05-00-036-03-02 utilized?
The assembly mounts mechanically onto a machine casing via its 3/4-14 NPT thread. The internal probe extends through the bearing housing to perform non-contact measurement of dynamic shaft variations without breaching the casing seal.
What is the primary function of the 21000-34-05-00-036-03-02?
The primary function is to provide external mechanical protection and environmental sealing for the sensitive internal 3300 XL probe, while allowing precise online adjustment and measurement of large-range shaft vibration, axial displacement, or differential expansion.
What type of probe is integrated within the 21000-34-05-00-036-03-02?
The assembly integrates a Bently Nevada 3300 XL 11 mm proximity probe (Option -34) with a probe cable length of 0.5 meters (Option -05).
What electrical and environmental certifications apply to the 21000-34-05-00-036-03-02?
The assembly carries Canadian Standards Association (CSA) approvals, meets CSA Type 4 (equivalent to IP66) enclosure ratings, and maintains explosion-proof and intrinsically safe ratings for hazardous locations.
